• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. hieu ((ve cam) or (ve cac)) suc danh thanh tai ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((ve cam) OR (ve cac)) suc danh thanh tai ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((ve cam) or (ve cac)) suc danh thanh tai ((cuu tre) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ((ve cam) or (ve cac)) suc danh thanh tai ((cuu tre) OR (cau tren))*.
